You are kidding, of course? You are marking a line 40 mils wide and
expecting a piece to come out to 20 mils or better accuracy?


If the line were 20 mils thick, where would you cut? The middle of the
line? The edge of the line?

But yes, a thin line is nicer.




When I started building I made up my on rule so I'd know which side to cut.
I always cut on the left edge of the mark. My reasoning is because I'm right
handed I will be holding the straight edge with my left hand and marking
with my right. With a very few exceptions this rule has served me well.

If I think there will be a question I put a little on the right(as opposed
to left) side.
